int STDCALL	closesocket (SOCKET s)
	Close an existing socket See the Windows Sockets documentation for additional information.
int STDCALL	connect (SOCKET s, SOCKADDR *name, int namelen)
	Establish a connection to a specified socket See the Windows Sockets documentation for additional information.
int STDCALL	ioctlsocket (SOCKET s, int32_t cmd, u_long *arg)
	Control the I/O mode of a socket See the Windows Sockets documentation for additional information.
int STDCALL	getpeername (SOCKET s, SOCKADDR *name, int *namelen)
	Retrieve the address of the peer to which a socket is connected See the Windows Sockets documentation for additional information.
int STDCALL	getsockname (SOCKET s, SOCKADDR *name, int *namelen)
	Retrieve the local name for a socket See the Windows Sockets documentation for additional information.
int STDCALL	getsockopt (SOCKET s, int level, int optname, char *optval, int *optlen)
	Retrieve a socket option See the Windows Sockets documentation for additional information.
u_long STDCALL	htonl (u_long hostlong)
